Answer:
- D: {-1, 0, 1, 4}; R: {-6, 3, 5, 7}
- D: {-1, 2, 3}; R: {3, 5, 7}
- D: {-2, -1, 0, 1}; R: {0, 1, 4}
Step-by-step explanation:
For relations expressed as (input, output) or (x, y) pairs, the domain is the list of inputs, or x-values. The range is the list of outputs, or y-values. Yes, it is that simple. (We often like to arrange the lists in increasing order.)

1. Domain: {-1, 0, 1, 4}
Range: {-6, 3, 5, 7}
__
2. Domain: {-1, 2, 3}
Range: {3, 5, 7}
__
3. Domain: {-2, -1, 0, 1}
Range: {0, 1, 4}
